11NIBE™ F2030Chapter 2 | The heat pump – the heart of the house

An air/water heat pump can use the outdoor air to heat a property. Theconversion of the outdoor air's energy to property heating occurs in threedifferent circuits. In the brine circuit, (1) , free heat energy is retrieved fromthe surroundings and transported to the heat pump. In the refrigerantcircuit, (2) , the heat pump increases the retrieved heat's low temperatureto a high temperature. In the heating medium circuit, (3) , the heat is dis-tributed around the house.

Outdoor airThe outdoor air is sucked into the heat pump.AThe fan then routes the air to theheat pump’s evaporator. Here, the air releasesthe heating energy to the refrigerant and the air's temperature drops. Thecold air is then blown out of the heat pump.

B

Refrigerant circuitA gas circulates in a closed system in the heat pump, a refrigerant, which alsopasses the evaporator. The refrigerant has a very low boiling point. In theevaporator the refrigerant receives the heat energy from the outdoor air andstarts to boil.

C

The gas that is produced during boiling is routed into an electrically poweredcompressor.When thegas is compressed, the pressure increases and the gas'stemperature increases considerably, from 5 °C to approx. 80°C.

D

From the compressor, gas is forced into a heat exchanger, condenser, whereit releases heat energy to the heating system in the house, whereupon thegas is cooled and condenses to a liquid form again.

E

As the pressure is still high, the refrigerant can pass an expansion valve, wherethe pressure drops so that the refrigerant returns to its original temperature.The refrigerant has now completed a full cycle. It is routed to the evaporatoragain and the process is repeated.

F

Heat medium circuitThe heat energy that the refrigerant produces in the condenser is retrievedby the climate system's water, heating medium, which is heated to 55 °C(supply temperature).

G

The heating medium circulates in a closed system and transports the heatedwater's heating energy to thehousewater heater and radiators/heating coils.

H

The temperatures are only examples and may vary between different installations andtime of year.

NIBE™ F2030Chapter 2 | The heat pump – the heart of the house12

Contact with F2030F2030has an integrated control system that checks andmonitors theheatpump operation. At installation the installer makes the necessary settingsof the control system so that the heat pump will work optimally in yoursystem.

The heat pump is controlled in different ways depending on what yoursystem looks like. If you have a NIBE indoor module heat pump operationcan be controlled from there. Refer to the relevant manual for further in-formation.


Maintenance of F2030Regular checks

When your heat pump is located outdoors some external maintenance isrequired.

NOTE

Insufficient oversight can cause serious damage to F2030 which is notcovered by the guarantee.

Checking grilles

Check that the inlet grille is not clogged by leaves, snow or anything elseregularly throughout the year.

Pay extra attention in event of high winds or snowfall that may cause thegrille to be blocked.

LEK/APH

Prevent snow building up and covering the grille on F2030.


LEK/APH

Keep free of snow and/or ice.

Cleaning the outer casing

If necessary the outer casing can be cleaned using a damp cloth.

Care must be exercised so that the heat pump is not scratched whencleaning. Avoid spraying water into the grilles or the sides so that waterpenetrates into F2030. Prevent F2030 coming into contact with alkalinecleaning agents.

Condensation drain pan and condensation water pipe

The trough and drain pipe may require cleaning from leaves or similarduring the year.

Cleaning1. Use the safety switch to cut the incoming electrical supply.

2. Release the trough using the quick release catches on the left andright front edges. Keep in position at the rear edgewithout stretchingthe power cable.

3. Clean drain pans and condensation water pipe/drains.

4. Reinstall the trough using the removal method in reverse order (seepoint 2).

5. Switch on the safety switch again.

In event of long power cuts

In the event of prolonged power failures it is recommended that the partof the heating system located outdoors is drained. Your installer has in-stalled a shut off and drain valve to facilitate this. Call and ask your installerif you are unsure.


Saving tips

Your heat pump installation produces heat and/or hot water. This occursvia the control settings you made.

Factors that affect the energy consumption are, for example, indoor tem-perature, hot water consumption, the insulation level of the house andwhether the house has many large window surfaces. The position of thehouse, e.g. wind exposure is also an affecting factor.

Also remember:

Open the thermostat valves completely (except those thermostats inthe rooms that are tobe kept cooler for various reasons, e.g. bedrooms).The thermostats slow the flow in the heating system, which the heatpumpwants to compensatewith increased temperatures. It thenworksharder and consumes more electrical energy.

Reduceor adjust the settings for heating in anyexternal control systems.

Energy meter

Check the accommodation's energy meter regularly, preferably once amonth. This will indicate any changes in power consumption.

Newly built houses usually have twin energymeters, use the difference tocalculate your domestic electricity.

New builds

Newly built houses undergo a drying out process for a year. The housecan then consume significantly more energy than it would thereafter.After 1-2 years the heating curve should be adjusted again, as well as theheating curve offset and the building's thermostat valves, because theheating system, as a rule, requires a lower temperature once the dryingprocess is complete.

Condenser

Heat exchanger where the hot gas state refrigerant condenses (cooledand becomes a liquid) and releases heat energy to the house heating andhot water systems.

COP

If it is stated that a heat pump has COP 4, this means, in principle that ifyou insert 10pence, youwill get 40penceworth of heat. It is the efficiencyof the heat pump. This is measured at differentmeasurement values, e.g.:7/45 where 7 stands for the outdoor temperature and 45 for howmanydegrees the supply temperature is.

Disturbances in comfort

Disturbances in comfort are undesirable changes to the hotwater/indoorcomfort, for example when the temperature of the hot water is too lowor if the indoor temperature is not at the desired level.

A malfunction in the heat pump can sometimes be noticed in the form ofa disturbance in comfort.

In most cases, the heat pump notes malfunctions and indicates this withalarms in the display.

Domestic hot water

The water one showers in for example.

Double-jacketed tank

A heater with domestic hot water (tap water) is surrounded by an outervesselwith boilerwater (to the house radiators/elements). The heat pumpheats the boiler water, which in addition to going out to the all the houseradiators/elements, heats the domestic hot water in the inner vessel.

Efficiency

Ameasurement of how effective the heat pump is. The higher the valueis the better it is.

NIBE™ F2030Chapter 5 | Glossary24
